Der volle Inhalt der QuelleThis dissertation is composed of two independent parts, sharing the common goal of developing stochastic models to study microbial evolution.The first part investigates the evolutionary impacts of population bottlenecks. Chapter one deals with microbial populations undergoing periodic bottlenecks. These dynamics correspond in particular to laboratory evolution experiments using serial dilutions to renew the medium in which bacteria grow. These wide variations in population sizes are also found in natural microbial populations, which undergo a bottleneck when transferred to a new host. However, the effects of successive dilutions on the evolution of these populations are not yet fully understood. Two effects have already been brought to light: reaching a large population size favors the appearance of rare mutations, and the loss of beneficial mutations during dilutions. We have developed a semi-deterministic model to study how these two phenomena combine and impact the evolutionary paths followed by the population as well as the adaptation rate on a minimal fitness landscape consisting of two types of beneficial mutations with the empirically supported trade-off between mutation rate and fitness advantage. Our model decouples the effect of two important parameters: the initial population size and the maximum population size of the initial strain. We find that low dilution and short cycles favor adaptation by the most frequent beneficial mutation, while strong dilution and long cycles favor adaptation by the most advantageous mutation. We also calculate the dilution rate maximizing the rate of evolution.The second chapter is a literature review on the effect of bottlenecks on the adaptive potential of populations, with a comparison between microbial and animal populations. We suggest ways in which microbial experiments could better inform conservation biology, notably by using yeast and including initial standing genetic variation.The second part looks at larger spatial and temporal scales, developing a stochastic model for macroevolutive gene dynamics in a bacterial species. Indeed, many bacterial species present an impressive gene diversity: the number of genes present in the species is frequently much greater than that carried by one cell, leading to the introduction in 2005 of the "pangenome" concept. Characterizing the dynamics of bacterial gene importations and horizontal transfers is crucial to understand the origins of this formidable diversity. These dynamics are also of great importance for public health, as they determine the spread of virulence and antibiotic resistance genes within bacterial populations. Over the past 10 years, several models have been formulated to describe the dynamics of bacterial genes along a phylogeny, but they remain unsatisfactory. These models take into account either the importation of genes into the focal species (by transfer from another species) or horizontal transfers within the species, but never both. We have therefore developed an original bacterial gene evolution model to take into account both inter- and intra-species transfer. Our model relies on three types of dynamics: persistent genes inherited from the ancestor, private genes that are clade-specific, and mobile genes undergoing frequent transfers. We have tested this model on a set of Salmonella enterica genomes, and shown that it is able to reproduce some important features of pangenomes, such as the U-shape of the gene frequency distribution and the parsimony of their arrangement on the core genome phylogeny. This model is able to classify genes according to their most likely dynamics, and the biological relevance of this classification has been confirmed by analyzing the function and position of genes assigned to each type

Der volle Inhalt der QuelleSoil microbial communities act as important agents of the biological soil functioning, particularly through their involvements in the transformations of biogeochemical cycles (C, N, P…). In agro-ecosystems, the diversity of these communities is affected by perturbations associated to agricultural practices, and the significance of these modifications in terms of preservation of biological functioning and sustainability of agricultural systems has emerged as a central issue in the environmental sciences. Whereas the role of biodiversity has been well studied for macroorganisms, in particular for plants; the biodiversity/activity relationship is still largely unknown for soil microorganisms. However, in the current agro-ecological movement, this knowledge is needed to define new agricultural practices including a best management of microbial diversity for the sustainable use of agro-ecosystems. In this context, the objective of this Phd was to test the significance of microbial diversity for the stability (resistance/resilience) and the activity of microbial community (bacteria and fungi) involved in the turnover of soil organic matter, a major function for soil fertility, environment quality and global changes. From an experimental point of view, these issues were addressed by coupling laboratory with field experiments. In a first work, by manipulating microbial diversity in laboratory condition, we have shown that the stability of both microbial genetic structure and activity in response to different perturbations is positively linked to microbial diversity (i.e. number of species). This link was then validated by a sampling based on a field experiment that allowed us to demonstrate that (i) the soil microbial diversity can be modulated (increased or decreased) depending the intensity of land use management, and (ii) the mineralization of organic matter is more intense in the soil with the highest level of diversity. Finally, thanks to an experiment carried out in the field (SOERE-ACBB, Lusignan), we showed that the response of bacterial and fungal communities to wheat residues supply in terms of successions of microbial populations and activities of organic matter mineralization depends on the soil management history. These works provide new insights into the significance of microbial diversity (richness, composition) for the stability and the activity of communities involved in the soil organic matter turnover. They also suggest that the modulation of the diversity of soil microbial communities by agricultural practices, past or present, can significantly affect the turnover of soil organic matter

Der volle Inhalt der QuellePatescibacteria is a highly diverse bacterial phylum, including at least 25% of the bacterial diversity. Representatives of this clade can be found in many environments, ranging from freshwater and marine ecosystems to animal microbiomes and sediments. Very few Patescibacteria cultures are available to date. Due to this lack of cultured representatives, they have been extensively studied using metagenomics. These investigations revealed that, overall, they present small genomes with significant gaps in the genes coding for metabolic functions, and thus, they are hypothesized to depend on a host for survival. There is no evidence, however, that all Patescibacteria are actual symbionts. Besides, about half of their genes cannot be functionally annotated by similarity approaches. More cultured representatives are needed to better understand the ecology of this bacterial phylum. Patescibacteria have been recently reported to be a sister group to the free-living phyla Chloroflexota and Dormibacterota. The evolution of the Patescibacteria, particularly their symbiotic lifestyle, and diversification from their free-living sister group, is not fully comprehended. Here, we obtained an enriched culture of a representative of a new genus-level patescibacterium, which is an epibiont of methanol-oxidizing proteobacteria, a type of host never observed before to be associated with this clade. Additionally, using a CRISPR-spacer match, we identified a new potential phage targeting this patescibacterium. Thus, we characterized the first potential three-partite interaction between a patescibacterium, its host, and a phage. Furthermore, we reconstructed the ancestral gene content of the different Patescibacteria classes to decipher the early steps of the evolution of the symbiotic lifestyle in the clade and the basis of their diversification. Our results suggest that the last common ancestor of Patescibacteria was already host-dependent. The subsequent patescibacterial diversification appears driven by a combination of independent and substantial losses of metabolic genes, complemented by the acquisition of novel genes with functions yet to be identified

Der volle Inhalt der QuelleAncestral and ubiquist ecosystems, microbial mats present an important biodiversity and a high metabolic richness. In coastal zone, these vertically laminated bacterial structures are exposed to diverse forms of contamination. Because they are main actors in biochemical cycles, the appreciation of contamination impact on these ecosystems is essential in microbial ecology. In this context, the present PhD study attempts specifically to better understand the impact of petroleum contamination on the complex bacterial community of microbial mats. The study is essentially based on microcosm experiments performed with different microbial mats. First, molecular approaches (T-RFLP and clone libraries analyses) based on 16S rRNA encoding genes allowed to follow during at least three months and up to one year of incubation, a petroleum pollution impact on bacterial communities of microbial mats. The study was also performed at the transcriptomic level (16S rRNA) in order to precise the response of metabolically active bacterial communities in these microbial structures. The main result of this work showed the resilience capacity of microbial mats. Afterward, the study of genes encoding for enzymes involved in hydrocarbon degradation (dioxygenases and benzylsuccinate synthase) have been performed in order to precise the functional response of microbial mats after petroleum contamination. Since the study of these functional genes could not relay the impact of petroleum we focused our study on new potentially involved genes. For this purpose, differential display approach on ARN was applied and allowed to display some gene/function potentially involved in microbial mat response after petroleum contamination
